ROLLERBEARING.

Specification of Letters Patent.

Patented Feb. 10, 1914.

Application led January 30, 1918. Serial No. 745,268.

To all whom 'it may concern Be it known that I, WILLIAM H. MA- KUTCHAN, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a new and useful Roller-Bearing, of which the followingis a specification.

One object of the present invention is to provide a bearing comprising inner and outer rings, adapted to rotate in alinement, or in intersecting planes, anti-friction means being interposed between the rings.

Another object of the invention is toprovide novel means whereby anti-friction elements may be held in operative relation to a pair of concentric rings.

With the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described, and claimed, it being understood that changes in the precise embodiment of ,invention can be made within the `scope of what is claimed without departing from the spirit of the invention.

In the drawings Figure 1 shows the invention in end elevation; Fig. 2 is a transverse section; Fig. 3 is an elevation of the spacing ring; Fig. 4 is a section taken longitudinally of the beal'in and at right angles to the showing of Fig. 2; and Fig. 5 is an elevation of one-roller. I

In carrying out the invention there is provided an inner ring 1, the opening 2 of which may beof circular form. The outer, peripheral face of the inner ring 1 is transversely concaved, asindicatedat 3. Projectingoutwardly from t-he conca-ved face 3 of the ring 1, intermediate the ends of the ring is a rib 4 which preferably is of triangular cross section.

The invention further includes an intermediate ring 5, within which the inner ring 1 is disposed. The intermediate ring 5 is equipped with a plurality of transverse openings 6,.so shaped that rollers 7 may be dropped into the openings 6 and be removed therefrom, after the intermediate ring 5 has been placed about the inner `r`ing 1. The rollers 7 are tapered from their central portions toward their ends, the rollers 7 being circumscribed by V-shaped grooves 8, adapted to receive .the rib 4 of the inner ring' 1. The inner face of the intermediate ring 5 is concaved as indicated at 9, so as to clear the Arib 4 of the inner ring 1. The outer face of the intermediate ring 5 is concaved .as shown at 10, so that, as indicated at 11 1n Fig. 2, the constituent material of the intermediate ring 5 will not overhang the rollers 7 and prevent the insertion and removal of the rollers 7 into the openings of the intermediate ring. Surrounding the intermediate ring 5 and the rollers 7 is an outer ring 12, the inner face of which is Yconcaved as shown at 14.

The faces 14 and 3 of the rings 12 andl respectively correspond to the longitudinal curvature of the rollers 7, so that the rollers 7 may have an adequate bearing upon the said faces. The curve of the inner face 14 of the outer ring 12 is struck upon an arc the center of which is the center of the opening 2 in the inner ring. As clearly shown in Fig. 4, the inner face 14 of the outer rin 12 is spaced, as indicated at 15, from the e ges of the intermediate ring 5;

As will be understood readily, the outer ring 12 may be held fixed, the ring 1 being rotatable, the rollers 7 constituting antifriction elements facilitating relative movement between the rings 1 and 12. If desired, however, the ring 1 may be held fixed, and the ring 12 may be rotatable, or both rings may rotate, each independently of the other.

The rings 12 and 1 are shown as in alinement in Fig. 4. However, it is to be observed that the rings12 and 1 may be tilted transversely, so that the same may rotate in intersecting planes. Under such 4circumstances, the ring 12 will move longitudinally of the rollers 7, the groove 8 and the rib 4 constituting interengaging elements for preventing the rollers 7 from moving transversely of the ring 1.

Having thus described the invention, what is claimed is 1. In a bearing of the class described, inner and outer rings; an intermediate ring located between the inner and outer rings and provided with transverse openings; and anti-friction elements in the openings, the anti-friction elements engaging the inner and outer rings, the intermediate ring bearing upon the inner ring at the ends of the anti-frictional elementsfand the anti-fric tion elements having superficial grooves, the inner ring having a circuinscribing rib engaging the grooves, to hold the intermediate ring upon the inner ring, the inner'face of ilo the outer ring being concaved and the antifriction elements being curved to correspond to the concavity of the outer` ring, thereby permitting the outer ring to tilt transversely, the outer face of the intermediate ring being spaced from the inner face of the outer ring to permit the tilting of the outer ring.l

2. In a bearing of the class described, an inner ring; an outer ring; an intermediate ring disposed between the inner` and outer rings and provided with transverse openings which taper toward their ends; rollers disposed in the openings and tapered toward their ends, the rollers engaging the inner and outer rings, the inner ring having a circumscribing rib and the rollers lhaving' grooves receiving the rib; the intermediate ring being of double concaved cr-oxss section to reduce the side friction upon the rollers, to permit said ring to clear the rib, and to prevent said ring from overhanging the rollers, whereby the rollers may be dropped into the openings.

In testimony that I claim the foregoing as my own, I have hereto affixed my signature in the presence of tWo witnesses.
